Description
Technical field
The present invention relates to colliery water spray dedusting valve technology field, be specifically related to a kind of automatic control intermittent valve.
Background technique
Dust in colliery can produce great harm to mine and operating personnel, therefore must carry out dedusting work to colliery.Comparatively conventional coal mine dedusting water spray projector system is intermittent valve, and general employing gas control or automatically controlled, structure and control procedure are relatively complicated.
Current intermittent valve be utilize enter epicoele quantitative water and discharge this gauge water needed time different, and the self-controlled on-off of valve realize interval-automatic circulate.The resistance that gauge water is overcoming the piston bearing certain pressure entering epicoele enters, therefore needed time is longer; When cavity of resorption pressure drop after valve open, the water of epicoele, under piston action, enters cavity of resorption by two channels, wherein large water gaging enters cavity of resorption through one-way valve, so needed time is extremely short, this time is the water discharging time of this valve, after epicoele gauge water is discharged, valve is just closed automatically.Major defect only takes valve body interval time apart could adjust, and when adjusting long interval time, the easy fouling and clogging of damping hole, causes interval malfunctioning, cause potential safety hazard to colliery.
Summary of the invention
The present invention is directed to the defect of prior art, the diaphragm type automatic control intermittent valve that a kind of structure is simple, reliable and stable, the intermittent time is easy to adjust is provided.
For solving the problems of the technologies described above, the present invention adopts following technological scheme: a kind of diaphragm type automatic control intermittent valve, comprises that screw rod, upper spring abutment, lower spring abutment, spring, supporting sleeve, piston, stem valve, valve seat, valve are stifled, barrier film, valve body, needle-valve, bearing ring, big spring and valve gap; The small end of described piston lower with the coaxial juxtaposition of the upper left chamber of valve body in the inner; The small end of stem valve is fixed in the center hole of piston upper insertion through chamber, valve body lower-left successively, and the lower end, chamber, lower-left of valve body is provided with valve seat, and the lower end of stem valve is docked with valve seat; Described supporting sleeve, spring and bearing ring respectively with stem valve and piston coaxial, and be placed in outside the bar of stem valve upper end successively, among the upper end hole of piston, and spring is outside supporting sleeve, under bearing ring; Connected firmly by screw thread with valve body in the right ports that the small end head of described needle-valve is placed in valve body inwardly, the upper left chamber of valve body and chamber, bottom right separate by needle-valve; Hydraulic oil is injected with in valve body upper left chamber and chamber, bottom right; The expansion platform hole in barrier film and chamber, valve body bottom right is coaxially placed in be expanded under platform and to touch, and is installed in valve body; There is between the chamber, lower-left of valve body and chamber, bottom right drainage channel be communicated with; Described valve blocks up coaxial with the respective aperture in chamber, valve body bottom right and forms valve body parts with its screw thread sealing; Screw flight one end under be placed in valve gap respective aperture and with its scyewed joint; The small end of upper spring abutment is placed in the respective aperture of valve gap upper; Big spring is coaxial with upper spring abutment, and its upper end be placed in spring abutment hole in and touch, the opening of lower spring abutment upper with valve gap coaxially and install and form valve gap parts in the inner; By valve gap parts, valve body parts and valve seat from top to bottom successively respectively screw thread connect firmly and seal ring sealing group integrally.
Further, also include pivot pin, described pivot pin to be through successively in bearing ring and stem valve upper end respective aperture and both to be connected firmly.
Further, be provided with some roads seal ring between described outer surface of piston and valve body upper left chamber inwall, seal ring is placed in the respective grooves of piston radial with piston coaxial respectively.
Further, also include pressure spiral shell, described pressure spiral shell is coaxial and with scyewed joint, barrier film is pressed solidly sealing with the chamber, bottom right of valve body.
The control procedure of this intermittent valve is as follows, when stem valve closes, flowing into chamber, valve body bottom right by drainage channel after liquid enters chamber, valve body lower-left from left side mouth acts under barrier film, along with the rising of liquid pressure, the hydraulic oil on barrier film top is forced to act on the piston lower portion of valve body upper left chamber by needle-valve, the resistance of further promotion piston overpowers spring, lower spring abutment and big spring moves up, and makes supporting sleeve and bearing ring rigid contact, and under promoting, spring abutment and big spring move upward; When the power of piston action on stem valve be greater than liquid pressure to stem valve under end plate upper surface formed pressure time, stem valve is broken instantaneously under the potential energy effect of spring, and now stem valve is in opening state;
During stem valve opening state, chamber, valve body lower-left liquid pressure reduces relatively, the pressure that the hydraulic oil of valve body upper left chamber is formed under the effect of piston and big spring is higher than the pressure of chamber, valve body lower-left liquid, the hydraulic oil of valve body upper left chamber flows on the barrier film of chamber, valve body bottom right by right ports and needle-valve, the liquid forcing barrier film to promote under it flows to chamber, valve body lower-left by respective aperture, piston, stem valve flows to chamber, valve body bottom right with hydraulic oil and moves downward under the effect of lower spring abutment and big spring, stem valve drops to close to valve seat moment, the pressure of valve body cavity of resorption improves because outlet relative area falls sharply, now act on the resistance that the pressure of end plate upper surface produces under stem valve power is greater than spring, stem valve is quick and valve seat is closed, now stem valve is in closed state.
Overall construction design of the present invention is more reasonable, completes tapping mode by the pressure of liquid, and working stability is reliable and the intermittent valve time is conveniently adjusted by needle-valve; Compact overall structure, volume is little, lightweight, good manufacturability, is convenient to assembling, adapts to field wide, and cost reduces by more than 30% than traditional batch valve, and working life doubles.
